HEAT PUMP APPARATUS

摘要

A heat pump apparatus comprises a heat pump cycle in which a refrigerant circulates through a compressor (31), a radiator (32), a throttle apparatus (33) and an evaporator (34) in this order, and an air duct (39) which envelops the radiator (32) and the evaporator (34), and which dehumidifies air from moisture absorbed from an object-to-be-dried by means of the evaporator (34) and which heats the air by means of the radiator (32). A rectifier apparatus (35) is provided at an inlet (39a) of the air duct (39). Drying air having stable and uniform air current distribution flows through the evaporator (34) and the radiator (32) to carry out effective heat exchange in the evaporator (34) and the radiator (32), and drying air having higher temperature and lower moisture is obtained.
